The visual hallucinations experienced by a 26-year-old woman under the influence of hallucinogens and during schizophrenia are described. Three types of hallucinations are delineated: (1) superimposed hallucinations, (2) spatial and depth distortions, and (3) animations. These three types of hallucinations appear to represent consecutive gradations on a continuum of the ego function of reality testing, with superimposed hallucinations revealing the least and animations the greatest degree of disorientation. The findings of the present study indicate the need for a research design that compares the hallucinations of schizophrenics to the toxic hallucinations of non-schizophrenics.
